GENIOSIL® TPTE
3-Mercaptopropyltriethoxysilane
GENIOSIL® TPTE is a clear, colorless liquid with a very characteristic odor.
特性
GENIOSIL® TPTE is an alkoxysilane with a Mercapto-functional group. It´s a clear, colorless liquid with a characteristic odor. As a bifunctional alkoxysilane, GENIOSIL® TPTE can also interact with numerous organic polymers and thus function as a molecular bridge between organic and inorganic substrates.
In addition to its application as an adhesion promoter in formulations and primers, GENIOSIL® TPTE functions as a surface modifier in fillers and pigments, where it improves the dispersibility of the filler and the mechanical properties - such as flexural strength, tensile strength and modulus - of the composites. The silane also reduces the filler's sedimentation tendency in the uncured polymer.
应用详细信息
1. General processing information:
GENIOSIL® TPTE is highly miscible with standard organic solvents such as ethers and hydrocarbons.
Mixing with alcohols other than ethanol leads to an autocatalytic exchange of alkoxy groups until the system reaches thermodynamic equilibrium.
Contact with moisture should be avoided during processing to prevent undesired hydrolysis.
2. GENIOSIL® TPTE as a surface modifier:
Fillers are treated either with pure GENIOSIL® TPTE or a solution thereof. It may be necessary to pretreat the substrate with water. The modified filler is preferably bonded to the organic material, e.g. a rubber, by mixing it with a standard curing agent.
In an alternative procedure referred to as "blending", GENIOSIL® TPTE is added directly to the polymer - either before the organic materials is compounded with the filler or at the same time.
A prerequisite for the blending process is that GENIOSIL® TPTE and the polymer are compatible and that the resin and GENIOSIL® TPTE do not react prematurely.
3. GENIOSIL® TPTE as an adhesion promoter in formulations:
In silane crosslinking formulations, GENIOSIL® TPTE may be added to the formulation as an adhesion promoter. Processing is effected by means of standard mixing methods. Usually, about 1 - 2 wt % silane is added to the formulation.
GENIOSIL® TPTE is used mainly as an adhesion promoter in elastomers, sealants, adhesives and coatings, and as a surface modifier for fillers (e.g. silica, glass, mineral wool, mica, metal oxides) and pigments.

储存
The ‘Best use before end’ date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
